Subject: s4:heimdal: import lorikeet-heimdal-201009250123 (commit
 42cabfb5b683dbcb97d583c397b897507689e382)

I based this on Matthieu's import of lorikeet-heimdal, and then
updated it to this commit.

+ * Michael Fromberger but has been written from scratch with
+ * additional optimizations in place.
+ *
+ * The library is free for all purposes without any express
+ * guarantee it works.
